aliases for products in multiple categories ?
How do you deal with url rewriting for products in multiple categories ?
Pathauto could(as far i know) generate only one url for each content, in this case we would need as much aliases as much categories.
ex: product1 has 3 categories and product2 has 1 category:
To avoid duplicate content, google recommends to insert main canonical url for duplicate content, in our case "node/nid"
Magento does this sort of things.
